GASOLINE FEED.

Application filed April 14, 1922. Serial No. 552,712.

To all whom it may concern:

Be it' known that I, PAUL M. Lnwis, a citizen of the United States,residing at Velpen, in the county of Pike and State of Indiana, haveinvented new and useful Improvements in Gasoline Feeds, of which thefollowing is a specification.

This invention relates to a gasoline feed mechanism for motor vehicles,and an object of the invention is to provide a gasoline reserve tankused in connection with the gasoline supply tank and carbureter of amotor vehicle for feeding gasoline to the carbureter irrespective of theincline over which the vehicle is traveling.

In certain types of motor vehicles, it is Well known that when thevehicle is climbing a hill and the gasoline supply is comparatively lowin the tank, that the gasoline will not properly feed to the carbureterconsequently the operation of the engine is stopped, and it is an objectof this invention to provide a siphon structure interposed between theconnection of the tank and carbureter which will feed gasoline to thecarbureter at all times irrespective of the relative elevations of thecarbureter and tank.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawing wherein:

Fig. 1 is a side elevation of the improved siphon showing it applied.

Fig. 2 is a top plan view of the improved siphon.

Fig. 3 is a longitudinal section through the siphon.

Fig. 1 is an end elevation through a modi fied form of the invention.

Fig. 5 is a vertical section taken on the line 55 of Fig. I.

Referring more particularly to the drawings, the improved gasoline orfuel feed siphon comprises a cylindrical body 1 which has a supportingstrap 2 engaging its outer surface intermediate its ends. The strap 2 isslotted as shown at 3 for engagement over a suitable bolt 1 carried bythe side of an engine A of a motor vehicle, for supporting the improvedsiphon in close proximity to the carbureter B. The tank 1 has its endssealed, preferably hermetically, and a fuel supply pipe 5 enters thetank through its rear end and extends through the length of the body, asclearly shown in Fig. 3 of the drawings. The pipe 5 has communicationwith the gasoline tank 6 of a vehicle equipped with the device to permitthe gasoline or other fuel to enter the cylindrical body 1. The innerend of the pipe 5 is out at an angle as shown at 5, so as to permit allof the liquid fuel to pass out of the pipe into the body 1. An outletpipe 7 is connected to the rear end of the body 1 at its lowermostportion and extends to and is connected with the inlet pipe 8 of thecarbureter B so that fuel will pass out of the body or tank 1 of thesiphon to the carbureter.

In gasoline supply systems, the tank 6 is provided with an air vent atits uppermost portion and the gravity action of the gasoline togetherwith the suction of the carbureter draws the gasoline from the tank andin the present'invention, these forces acting, will fill the tank orbody 1 of the siphon structure, the lowermost portion of which ispractically on a level or slightly above the top of the carbureter B andthe fuel will flow from the body 1 into the carbureter until the body 1has a predetermined capacity, preferably one pint and it will beapparent that during travel of a vehicle equipped with the device thetank or body 1 will be full at all times and thus when the vehiclestarts up an incline the angle of which is sufficient to bring thecarbureter B above the elevation of the tank 6 the gasoline or fuel willfeed to the carbureter from the tank or body 1 while without the use ofthe siphon structure, in cases where the gasoline is low in the tank 6,such feeding of gasoline would be out off preventing operation of thevehicle.

An air vent 9 is formed in the casting 10 which is attached to the body1 and it has communication through the longitudinal bore 11 of thecasting with the interior of the tank or body 1 to permit release of airfrom the tank to prevent the feed from becoming air bound. A rod 12 isslidably mounted in the bore 11 and extends up- 'Wardly therefromthrough the dash G of the motor vehicle, having a thumb nut 13 mountedupon its outer end to facilitate its sliding movement in the bore 11 foropen ing or closing the vent 9. A spring 14 is coiled about the rod 12and engages a dash carried guide 15 for urging the rod into vent closingposition.

In Figs. 4; and 5 of the drawings a slight modification of the gasolinefeed structure is shown in which the inlet pipe 5 enters the tank 1adjacent its lowermost portion ners and the parts associated indifferent relations and, therefore, I do not desire to be limited in anymanner except as set forth in the claim hereunto appended.

Having thus described my invention What I claim is:

An auxiliary fuel tank for motor vehicles 15 having an inlet pipeentering one end of the tank adjacent the top thereof and extending intothe tank for nearly its entire length, the inner end of said pipe beingcut at an angle,

an outlet pipe leading from the same end of 0 the tank that the inletpipe enters but at a point adjacent the opposite Wall, an air regulatingpipe for the tank consisting of a vent pipe section extending upwardlyfrom the tank, and aslidably mounted rod for 25 opening and closing thepipe section.

In testimony whereof I affix my signature.

PAUL M. LEWIS.
